[U-Boot] Failure in ubifsmount

[Stefano Babic]

Hi,

it seems I have found an unitialized variable when I run ubifsmount on
an ARM board.

The problem arises during the sget() function when the "type" of
filesystem is added to the superblock list, at the following line:

	list_add(&s->s_instances, &type->fs_supers);

I have checked that fs_supers has both pointers prev and next set to
zero. The pointer type is only a reference to the static structure
ubifs_fs_type, inside the same file, and the fs_supers is not
initialized at all.
Initializing the list with INIT_LIST_HEAD seems solving the problem,
after that ubifsmount works and I can load files with ubifsload.
However, I am not sure if this is enough (else I had sent a patch...).

Regards,
Stefano
